Description

Guide rails for sliding door fittings

technical field

The present invention relates to a guide rail for sliding door fittings, in particular for furniture, household appliances or partition walls, having at least two slideways for rollers, which in vertical direction Offset settings relative to each other.

Background technique

DE 255 31 75 discloses a sliding door fitting in which guide rails are fixed on a top plate in which the slideways are arranged one above the other. As a result, a particularly compact structure results, in which the profile is formed in one piece as an extruded profile. The extruded profile does have a high stability, but also a high material consumption due to the thick walls. This makes the production of extruded rail profiles expensive.

Contents of the invention

It is therefore an object of the present invention to provide a guide rail for sliding door fittings which is simple to produce and cost-effective.

This object is achieved by a guide rail for a sliding door fitting having the features of claim 1 .

According to the invention, the guide rail is produced in one piece from bent plates, resulting in a reduced material usage compared to extruded profiles. As a result, the guide rail can be produced efficiently and cost-effectively, wherein also a smaller number of pieces can be produced.

According to a preferred embodiment of the invention, the curved plate has a thickness of between 0.4 mm and 3 mm, in particular 0.5 mm to 1.5 mm. Thus, the guide rails can be produced depending on the weight load, wherein guide rails for smaller and lighter sliding wings can be formed thinner than guide rails for heavier sliding doors.

The first slideway and/or the second slideway are preferably formed to be curved or V-shaped in cross section. Thus, the slideways are able to provide good lateral stability during guidance in which the rollers move in a self-centering manner on the guide rail due to the weight load.

According to a preferred embodiment, the guide rail at least partially has a contact bend or almost a contact bend, if spring-out of the plate cannot be completely avoided after the bending process. These (almost) contacts increase the stability of the guide rail and can optionally be fastened by means of, for example, integral joints by means of welding or gluing, or by other fastening means (for example by rivets, screws), or The contacts are additionally connected (almost connected) by means of forming techniques, for example by riveting or embossing. Due to the (almost) contact portions, which are optionally additionally fixed to one another, a particularly dimensionally stable guide rail results. In the present example, the slideways are arranged vertically offset relative to each other, ensuring good leverage conditions so that large forces can be absorbed with a thin steel plate. Even with an additional fastening of the parts abutting against each other, the production of such guide rails can be carried out industrially with high quality and efficiently.

In a preferred embodiment of the invention, the guide rail has horizontal legs which can be fixed to the bottom or top plate of cabinet-like furniture. To this end, the guide rail can be screwed to the upper side or the end side of the top plate. The guide rail may then have an upper vertical leg adjoining an upper horizontal leg, wherein a horizontal protrusion is provided on the lower leg to form the first slideway. For a particularly compact construction, a second lower vertical leg is additionally provided on the rail, which second lower vertical rail is arranged at least partially below the upper vertical leg and has a horizontal projection on the underside to form a Second slide. In this embodiment, the upper and lower vertical legs can be arranged in one plane so that the two legs at least partially press against the end sides of the top or bottom plate, which increases stability . It is also possible to offset the upper and lower vertical legs relative to each other in different planes, thereby providing a more stepped configuration of the rail, which enables the use of structure space.

In the guide rail according to the invention, preferably a recess is provided for protruding from the tractor or the drive of the damping device. It is thus possible to place self-tractors or damping devices discreetly behind the guide rail, which improves the appearance.

A sliding door fitting can have a guide rail according to the invention, wherein a plurality of such guide rails can be fixed relative to each other by means of butt connectors. For this purpose, the guide rail can have one or more hollow spaces into which corresponding connecting elements are inserted.

At least one roller movable in the upper guide path of the guide rail 4 is guided on a cage 7 . FIG. 2 also shows a housing 11 of a self-retractor or damper, preferably of the damped type, having a drive 10 that engages an activator 9 connected to the cage 7 . The sliding doors 5 and 6 can be decelerated or held by the damping type self-tractor in both the opening direction and the closing direction. In the present example, the drive 10 is guided through a recess in the guide rail 4 .

FIG. 3 shows the suspension of the rear sliding door 6 . At the rear of the rear sliding door 6 is fixed a cage 8 which engages via an activator 9 with a drive 10 of a self-tractor or damper. In the present example, the drive 10 is held movably on a housing 11 of a self-tractor or damper, wherein the drive 10 is also engaged by a recess in the rail 4 . In the present example, the rear sliding door 6 is movably held in the glide path 21 of the guide rail 4 by means of at least one roller.

A side view of the guide rail 4 is shown in FIG. 4 , and it can be seen that the front sliding door 5 is movably held on the upper slideway 20 by the rollers 12 and the rear sliding door 6 is movably held on the lower slideway by the rollers 12. 21 on. The roller 12 has a V-shaped support surface, and the slides 20 and 21 also form a V-shaped section. Of course, other geometries are also conceivable, for example curved support surfaces in concave or convex form and inverted V-shaped support surfaces.

FIG. 5 shows a cross-sectional view of the guide rail 4 . The guide rail 4 consists of a bent steel sheet having a thickness of between 0.4 mm and 3 mm, in particular 0.5 mm to 1.5 mm. In the present example, the guide rail 4 comprises an upper leg 22 which can rest on the top plate 3 or the bottom plate. The first vertical leg 23 is adjacent to the horizontal leg 22 , and on the underside of the first vertical leg 23 , the protruding horizontal portion forms the upper slideway 20 . To this end, webs 24 and 25 arranged in a V shape are provided, wherein an outer vertical edge 26 is formed on the outer web 25 which prevents the roller 12 from jumping out towards the front. Before the two V-shaped webs 28 and 29 arranged on the underside, which run parallel to the webs 24 and 25 , the transition 27 adjoins the edge 26 at the bottom. In the region of the upper runner 20 , the steel plate of the guide rail 4 is doubled, so that the upper runner 20 has increased stability. The (nearly) contact portions of the guide rail 4 can additionally be fixed to each other, for example by welding, gluing, profiling or other measures, in order to increase the stability of the guide rail 4 .

Adjoining the web 29 , a second vertical leg 30 has a horizontal protrusion on the underside to form the glideway 21 . In the present example, the vertical legs 23 and 30 are arranged in one plane and can be pressed at least partially against the end sides of the top plate 3 . The glideway 21 is also formed by two webs 31 and 32 arranged in a V shape, wherein an upwardly protruding edge 33 is formed on the outer web 32 to prevent the rollers 12 from jumping out.

In the following FIGS. 6 to 12 , exemplary embodiments of modifications of the guide rail according to the invention are shown, wherein the same parts as the guide rail 4 in FIG. 5 are designated with the same reference numerals and only for The modified part is explained.

Figure 6 shows a guide rail 4' wherein the upper horizontal leg 22' has a slightly raised middle portion and two depressed edge portions. Thus, the horizontal leg 22' rests against the top plate 3 only with its edge.

Furthermore, in the guide rail 4 ′ in FIG. 6 , the area below the web 25 is changed, since in this area the guide rail 4 ′ does not form a double wall, but the web 28 ′ is arranged spaced apart from the web 25 . In contrast, the web 24 is supported by the lower web 29 of the guide rail 4 ′, so that a certain stabilization is provided due to the double wall structure in at least this area. The slideway 20 is mechanically stabilized as a whole by the vertical transition 27 ′ formed on the horizontal web 28 ′, since it is supported on the web 25 . In other respects, this exemplary embodiment corresponds to FIG. 5 .

FIG. 7 shows a modified guide rail 4 ″ in which a longer horizontal leg 22 ″ rests against the top plate 3 . In this example, the legs 22" are formed linearly and merge into the vertical legs 23 after a bend. In this embodiment, the web 25 is also formed with only one wall on the runner 20 without is supported by the further part of the guide rail 4" (because the web 28" is arranged spaced apart from the web 25). Between the web 28" and the vertical edge 26 there is provided a vertical Straight portion 27". Instead, the web 24 is supported by the lower web 29.

Furthermore, in FIG. 7 the area of the glideslope 21 is slightly modified, since the edge 33 does not stop at the vertical, but is bent by a fold 34 so that a vertical 35 and a portion facing obliquely outwards are provided 36. Therefore, one edge of the portion 36 is relatively concealed. In the case of particularly high g-forces, the slideway 21 may be supported by a slightly upwardly sloping portion 36 . It is also possible to connect the web 32 to the portion 36 in one piece, for example by gluing or welding.

In FIG. 8, the area below the upper runner 20 has been modified in the guide rail shown. The vertical leg 50 adjoins the edge 26 and merges into the horizontal web 51 before the vertical leg 30 is formed on the guide rail, on the underside of which the glideway 21 is provided. Thus, the upper runner 20 is formed entirely by one wall and is spaced apart from the horizontal web 51 .

In FIG. 9 , the guide rail 4 is substantially modified in the area of the glideslope 21 , since adjacent to the vertical edge 33 a fold 34 and a downwardly directed vertical portion 35 are provided.

In FIG. 10 , the guide rail 4 is also modified in the region of the glide path 21 , since, compared to FIG. 9 , the V-shaped webs 37 and 38 also adjoin, which support the webs 31 and 32 . Both the upper slide 20 and the lower slide 21 form a double wall, making the slides 20 and 21 particularly stable.

In FIG. 11 , a slight modification with respect to FIG. 10 is shown, in which the glideway 21 is double-walled on one side only by webs 37 .

Figure 12 shows another embodiment of the guide rail, wherein the upper vertical leg 23' is laterally offset relative to the lower vertical leg 30'. The upper runner 20' is formed on the upper vertical leg 23', which is no longer formed in a V shape, but bent upwards. To this end, the upper runner 20 ′ is supported on two vertical webs 60 and 61 . The horizontal web 62 adjoins the web 61 which presses against the vertical web 60 at the bend, wherein the web 60 and the web 62 can be fixed to each other at the contact area for added stability. The lower vertical leg 30' is arranged in the plane of the vertical web 60, and the lower side of the lower vertical leg 30' is adjacent to the glideway 21', which is similar to the upper glideway 20' and is roughly formed A square profile with curved upper sides.

An arrangement is also conceivable in which the legs 23' and 30' are arranged vertically in one plane.

FIG. 13 shows the guide rail shown in FIG. 12 with a sliding door fitting, with rollers 12 ′ on the cage 7 and rollers 12 ′ on the cage 8 . The rollers 12' are guided on the upper slides 20' and the lower slides 21', wherein the rollers 12' form a curved or V-shaped cross-section and are guided in a self-centering manner on the slides 20' and 21'. lead. To this end, the roller 12 ′ has a transverse edge 70 with a larger diameter than the runner 71 .

Figures 14 and 15 show the connection of two guide rails 4" at the butt joint (i.e. on the end side). The cross section of the guide rail 4" is similar to that of Figure 7, wherein, in order to connect the two guide rails 4", the The connecting element 40 is inserted into a hollow cavity 41 formed by the curved profile of the guide rail 4". The connecting element 40 is triangular in cross-section and can be inserted into the hollow cavity below the outer web 25 of the upper runner 20 and the lower web 32 of the lower runner 21 . On the glideslope 21 , the end 36 is slightly extended with respect to FIG. 7 , so that a closed cavity is created.

FIG. 16 shows an embodiment with a cross-sectional profile corresponding to FIG. 5 , in which the guide rail 4 is fastened to the top plate 3 . For a more stable fixation, an angled reinforcement element 80 is fixed (in particular screwed) on the underside of the top plate 3, and this reinforcement element 80 can also be fixed to the guide rail by gluing, screws or other fastening means 4 on the vertical contact surface.

Figure 17 shows a guide rail in which two slideways 20 and 21 arranged one above the other are provided, each formed by bending edge portions of steel plates, while the middle portion is guided at an angle with respect to the upper side of the top plate . Therefore, the part that rests on the top plate is implemented as double-walled.

Figure 18 shows a cross-section of a guide rail with two slides 20 and 21 placed one above the other, wherein the vertical section 23 above the slideway 20 and the vertical section 30 of the slideway 21 are arranged above the slideways 20 and 21 the opposite side of .
